Sets an offset in a larger frustum. This is useful for multi-window or multi-monitor/multi-machine setups. For example, if you have 3x2 monitors and each monitor is 1920x1080 and the monitors are in grid like this:
+---+---+---+
| A | B | C |
+---+---+---+
| D | E | F |
+---+---+---+
then for each monitor you would call it like this:
const w = 1920;
const h = 1080;
const fullWidth = w * 3;
const fullHeight = h * 2;
// A
camera.setViewOffset( fullWidth, fullHeight, w * 0, h * 0, w, h );
// B
camera.setViewOffset( fullWidth, fullHeight, w * 1, h * 0, w, h );
// C
camera.setViewOffset( fullWidth, fullHeight, w * 2, h * 0, w, h );
// D
camera.setViewOffset( fullWidth, fullHeight, w * 0, h * 1, w, h );
// E
camera.setViewOffset( fullWidth, fullHeight, w * 1, h * 1, w, h );
// F
camera.setViewOffset( fullWidth, fullHeight, w * 2, h * 1, w, h ); Note there is no reason monitors have to be the same size or in a grid.
